FAQ

1. Does the AAI135-H50/13S00 support hot-swap capability?

   No, this module does not support hot swapping. The system must be powered down before replacement.

2. Can I configure individual channels for different input types (e.g., voltage)?

   No, all channels are fixed for 4–20 mA input. Voltage input requires external signal conditioning.

3. Is HART communication enabled by default on all channels?

   Yes, HART is available on all 16 channels if the system configuration and wiring support it.

4. How is signal isolation implemented between channels?

   Each channel is galvanically isolated to prevent mutual interference and protect the system from ground loops.

5. Can the module be used in redundant I/O configurations?

   Yes, it can be used in redundant I/O systems when paired with appropriate baseplates and configuration.

6. What diagnostics does the module offer for input loop monitoring?

   The module supports open circuit, over-current, and short-circuit detection diagnostics for each channel.

7. Is the module suitable for SIL3 applications?

   Yes, when configured within a certified ProSafe-RS system, the module supports SIL3 operations.

8. How is configuration handled for this module?

   Configuration is performed using Yokogawa’s engineering tools such as SENG and PRM.

9. Can the module detect loop polarity errors?

   No, polarity reversal protection is typically handled by field instruments or wiring design.

10. Is channel calibration required?

    The module is factory-calibrated and does not require field calibration under normal operation.
